of on the left. have you had people of all stripes crunching these numbers ever since mitt romney said let's cap deductions and the answer is the money is there if is he willing to abandon this kind of liberal orthodoxy that you have to raise tax rates. >> bring in 749 billion in extra revenue to do that. >> to limit deductions, to $50,000 a year, that would bring in 749 billion. how much would letting the tax cuts, the bush tax cuts expire for those making 250 and up? >> expirations he wants to allow 800 billion. that's what analysts have said on all sides have said that's what you can get if you limit deductions. in fact, the romney plan, capping deductions at $17,000 i think everyone agrees it would give you more than the president is asking for this 1.6 trillion. >> alisyn: that's right. that's what the tax policy center did he dued that romney's plan capping at 17,000 bring in more. how can both sides be so far apart? are they just playing chicken with each other okay i will let you go off the fiscal cliff. you let me go of o00 fiscal cliff what's going to happen? >> it's a weird scenario.
